PHP error - Deprecated: Function ereg_replace() is deprecated

Hi,
I am receiving the following error message and would like to know if I should replace all occurrences of ereg_replace with preg_replace in my code and do I need to change anything else?

Deprecated: Function ereg_replace() is deprecated in /home/mywebsite/public_html/admin/website_settings.php on line 797
   
                              
$imagesml = ereg_replace ( '.jpg', '_med.jpg',  $row_view_tbl["image1"]);
$temps[$j] = ereg_replace ( '.jpg', '_sml.jpg', $temp[$j]);

Thanks in adavance for you feedback.

Yes, they need to be changed, but it's not as simple as changing the function name. How many occurrences do you have? It's pretty quick for me to convert them:

$imagesml = ereg_replace ( '.jpg', '_med.jpg',  $row_view_tbl["image1"]);
$imagesml = preg_replace ( '/\.jpg/', '_med.jpg',  $row_view_tbl["image1"]); #Escaped the . to treat it as a literal period rather than a wilcard


$temps[$j] = ereg_replace ( '.jpg', '_sml.jpg', $temp[$j]);
$temps[$j] = preg_replace ( '/\.jpg/', '_sml.jpg', $temp[$j]); #Escaped the . to treat it as a literal period rather than a wilcard

Note the eregi_replace function is affected too.

I am not recommending this as  along-term strategy, but you can also turn off the Deprecated messages.  That might be a good solution short term.

Add this to the top of your script:
error_reporting(E_ALL ^ E_DEPRECATED);

Since this message is occurring as a byproduct of a PHP upgrade migration, you may want to know about other PHP upgrade issues.  These articles cover a couple of the issues.

Thanks for your feedback, I probably have about 100 occurrences throughout my website.
If I set  error_reporting to hide the messages I am assuming that the ereg_replace will still work, is that correct and if so for how long?

Yes, that is probably correct.  And it is correct until it is no longer correct.  In other words, the period of success is unpredictable and you want to fix the issue ASAP.

Here is what I have experienced.  My host upgraded PHP.  I started getting a lot of awful messages.  I turned the "deprecated" messages off.  I used a code scanner to find all of the ereg() related function calls.  I corrected the lines with these functions (there were hundreds).  After I corrected each of the deprecated function calls, I tested the scripts by setting up a test case with deprecated messages set to "on" and once the test cases were satisfied, I committed the script revisions.  In my experience with a thousand-script site, this took about a full day but I still had time to go to lunch.

YMMV, and I wish you the best of luck, ~Ray

100 occurrences doesn't take long to convert - feel free to post them.

Thanks for your help, much appreciated.
I have about 100 occurrences but most are the same repeated throught the site so really I just have 5 similar ones which are shown below.

$imagesml = "/".ereg_replace ( '.jpg', '_swg.jpg',  $row_view_photos1["image1"]);
$image1 = ereg_replace ( '.jpg', '_swg.jpg',  $image1);
$imagesml1 = ereg_replace ( '.jpg', '_sml.jpg',  $row_view_tbl["image1"]);
$release = ereg_replace('^([[:digit:]]+\.[[:digit:]]+).*', '\1', $parts[2]);
$release = ereg_replace('-.*', '', $parts[2]);

$release = preg_replace('/-.*/', '', $parts[2]);

Where I've added a comment, I've actually altered the pattern functionality slightly - because the . character is a wildcard, this code:
ereg_replace ( '.jpg', '_swg.jpg',  $image1);
would have changed the value "foodjpg" to "foo_swg.jpg". ie it didn't actually require a . character in the filename. I changed the . to \. so that the character is treated literally rather than as a wildcard.
